Windows is Slow...

The parser seems incredibly slow on my Windows NT/IIS4 machine.

I have been running simple tests with apachebench, to try to get a good
view of the problem. Here are some numbers:

100k html, no php: 18 seconds
50k html, no php: 9 seconds
25k html, no php: 4.8 seconds
100k php comment: 5 seconds
50k php comment: 2.8 seconds
25k php comment: 1.7 seconds

html above meaning that the .php file didn't actually include any <?php
?>
tags. It seems the php engine running through html is actually slower
than
compiling php code.

As for network speeds, the transfer rate I get for the straight html
..php
files is 6kB/sec, while ftp to the server gets 900kB/sec.

Now, what could I be doing wrong here? The same 100k file with the CGI
php3 takes 0.3 seconds to load. Eh? php 3 I said! Does it make
sense that
php3 is 10-20 times FASTER than php4?

The CGI version of php4 is not much slower than the ISAPI module
(I'm sure its easy to loose the difference
when it takes 10 seconds to load a page). I wast starting to believe
that all the new optimizations were slowing down the bulk moving of html

across the wire, so I tried the same tests on linux/apache/mod_php4,
and couldn't get the page to load any slower than 0.02 seconds.
Unfortunately, I can't run this stuff on linux at the moment, as it
depends on a couple dlls that are currently only available with NT.

I've tried other machines with the same results. The 'optimized' php
file is
just as slow.

Can anyone reproduce my results? Is not sending 50k
of html through the server a common thing?
I can't believe others are not complaining about this.
